Fifa has confirmed that 13 member associations have registered for the right to host the 2018 or 2022 World Cup.
All those who made an initial expression of interest in staging one or both of the events in February remain in the running after the 16th March deadline for applications.
That means Australia, Belgium and Holland, England, Indonesia, Japan, Mexico, Russia, Spain and Portugal, and the USA are all in the running for both competitions.
Meanwhile, South Korea and Qatar have registered bids for the 2022 showpiece.
The final decision will be made on 11th December 2009.
